Struct nrf51_hal::Spi

pub struct Spi<T>(_);

Interface to a SPI instance.

Implementations

impl<T> Spi<T> where
    T: Instance, 

pub fn new(spi: T, pins: Pins, frequency: FREQUENCY_A, mode: Mode) -> Spi<T>

pub fn free(self) -> T

Return the raw interface to the underlying SPI peripheral.

    T: Instance,
    Spi<T>: FullDuplex<u8>, 

impl<T> Default<u8> for Spi<T> where

impl<T> Default<u8> for Spi<T> where
    T: Instance,
    Spi<T>: FullDuplex<u8>, 

impl<T> FullDuplex<u8> for Spi<T> where
    T: Instance, 

type Error = Error

An enumeration of SPI errors

pub fn read(&mut self) -> Result<u8, Error<<Spi<T> as FullDuplex<u8>>::Error>>

Must only be called after send as the interface will read and write at the same time.

pub fn send(
    &mut self,
    byte: u8
) -> Result<(), Error<<Spi<T> as FullDuplex<u8>>::Error>>

Must only be called the same number of times as read.

nRF51 is double buffered; two bytes can be written before data must be read.
